A ProoV case study · educational project, not employment
Built an end-to-end profit-paradox analysis: framed the business problem with a KPI driver map and data audit, wrote correct SQL to compare category and regional margins, and isolated the main profit drivers through a structured root-cause view. Also translated the findings into an executive narrative and recovery scenario focused on margin repair without sacrificing growth.

What stood out6
- Correctly computed category margin as (revenue − cost) / revenue and used GROUP BY with ordered comparison across categories.
- Joined regional discount data to margin analysis and tied the weakest margin region to the highest discounting pattern.
- Built a clear profit-bridge narrative that prioritised raw-material inflation, logistics inefficiency, and discounting as the main causes.
- Translated the analysis into stakeholder-facing language that distinguished profitable growth from unprofitable volume.
- Structured Problem Framing
- Leakage-Free SQL Aggregation
